Can someone help me with inequalities please

Solve the inequality 4x - 6 > 6x - 20collect like terms.subtract 4x from both sides,......
this first before you look at the multiple choices. Don't try to eyeball guess the answer
to the multiple choice question before you have simplified the problem.

For the first set translate: 2x + 1 greater than or equal to 19?
becomes
2x + 1 >= 19

Right off the bat, you can simplify this into a couple of equivalent statements.
1) subtract 1 from each side of the equation

2x >= 18

divide both sides by 2

x >= 9

So now look at the rest of the question. Immediately you can see that the first
statement is true.

We can write x > = 9 as:
x > 9 or x =9

so that shows that the second statement of 9 < x or 9 > x is not correct.

the third statement is a description of a picture. Draw a numberline, and shade
the point at x=9 as a big black dot, then draw a heavy line to the right, This
would be the correct picture.

The fourth statement is reversed and so is false.


Solve the inequality 4x - 6 > 6x - 20

collect like terms. subtract 4x from both sides, and add 20 to both sides

14 > 2 x

divide both sides by 2

7 > x
12
